### 1、修改密码 ###

MySQL [(none)]> SET PASSWORD FOR 'root' = PASSWORD('123456');
    Query OK, 0 rows affected (0.01 sec)
    
    MySQL [(none)]>

MySQL [(none)]> exit
    Bye
    [root@node3 fe]# mysql -h 10.17.12.160 -P 9030 -uroot -p123456 
    Welcome to the MariaDB monitor.  Commands end with ; or \g.
    Your MySQL connection id is 1
    Server version: 5.1.0 Doris version 0.12.0-rc03

    Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
    
    MySQL [(none)]>

### 2、创建数据库 ###

MySQL [(none)]> CREATE DATABASE tpa;
    Query OK, 0 rows affected (0.00 sec)
    
    MySQL [(none)]> show databases;
    +--------------------+
    | Database           |
    +--------------------+
    | information_schema |
    | tpa                |
    +--------------------+
    2 rows in set (0.01 sec)
    
    MySQL [(none)]>

其中，information\_schema是为了兼容MySQL协议而存在

### 3、创建新用户 ###

MySQL [(none)]> CREATE USER 'test' IDENTIFIED BY 'test';
    Query OK, 0 rows affected (0.01 sec)
    
    MySQL [(none)]>

### 4、授权 ###

MySQL [(none)]> GRANT ALL ON tpa TO test;
    Query OK, 0 rows affected (0.01 sec)
    
    MySQL [(none)]>

[root@node3 fe]# mysql -h 10.17.12.160 -P 9030 -utest -ptest
    Welcome to the MariaDB monitor.  Commands end with ; or \g.

    Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
    
    MySQL [(none)]> use tpa;
    Database changed
    MySQL [tpa]>

### 5、建表 ###

Doris支持支持单分区和复合分区两种建表方式。

（1）建立一个名字为 table1 的单分区表。分桶列为 siteid，桶数为 10。

建表语句：

CREATE TABLE table1
    (
        siteid INT DEFAULT '10',
        citycode SMALLINT,
        username VARCHAR(32) DEFAULT '',
        pv BIGINT SUM DEFAULT '0'
    )
    AGGREGATE KEY(siteid, citycode, username)
    DISTRIBUTED BY HASH(siteid) BUCKETS 10
    PROPERTIES("replication_num" = "1");

建表操作如下：

MySQL [tpa]> CREATE TABLE table1
        -> (
        ->     siteid INT DEFAULT '10',
        ->     citycode SMALLINT,
        ->     username VARCHAR(32) DEFAULT '',
        ->     pv BIGINT SUM DEFAULT '0'
        -> )
        -> AGGREGATE KEY(siteid, citycode, username)
        -> DISTRIBUTED BY HASH(siteid) BUCKETS 10
        -> PROPERTIES("replication_num" = "1");
    Query OK, 0 rows affected (0.32 sec)
    
    MySQL [tpa]>

（2）建立一个名字为 table2 的复合分区表。  
使用 event\_day 列作为分区列，建立3个分区: p201706, p201707, p201708

*  p201706：范围为 \[最小值, 2017-07-01)
 *  p201707：范围为 \[2017-07-01, 2017-08-01)
 *  p201708：范围为 \[2017-08-01, 2017-09-01)

建表语句：

CREATE TABLE table2
    (
        event_day DATE,
        siteid INT DEFAULT '10',
        citycode SMALLINT,
        username VARCHAR(32) DEFAULT '',
        pv BIGINT SUM DEFAULT '0'
    )
    AGGREGATE KEY(event_day, siteid, citycode, username)
    PARTITION BY RANGE(event_day)
    (
        PARTITION p201706 VALUES LESS THAN ('2017-07-01'),
        PARTITION p201707 VALUES LESS THAN ('2017-08-01'),
        PARTITION p201708 VALUES LESS THAN ('2017-09-01')
    )
    DISTRIBUTED BY HASH(siteid) BUCKETS 10
    PROPERTIES("replication_num" = "1");

操作如下：

MySQL [tpa]> CREATE TABLE table2
        -> (
        ->     event_day DATE,
        ->     siteid INT DEFAULT '10',
        ->     citycode SMALLINT,
        ->     username VARCHAR(32) DEFAULT '',
        ->     pv BIGINT SUM DEFAULT '0'
        -> )
        -> AGGREGATE KEY(event_day, siteid, citycode, username)
        -> PARTITION BY RANGE(event_day)
        -> (
        ->     PARTITION p201706 VALUES LESS THAN ('2017-07-01'),
        ->     PARTITION p201707 VALUES LESS THAN ('2017-08-01'),
        ->     PARTITION p201708 VALUES LESS THAN ('2017-09-01')
        -> )
        -> DISTRIBUTED BY HASH(siteid) BUCKETS 10
        -> PROPERTIES("replication_num" = "1");
    Query OK, 0 rows affected (0.29 sec)
    
    MySQL [tpa]>

### 6、查看表信息 ###

MySQL [tpa]> SHOW TABLES;
    +---------------+
    | Tables_in_tpa |
    +---------------+
    | table1        |
    | table2        |
    +---------------+
    2 rows in set (0.00 sec)
    
    MySQL [tpa]> DESC table1;

    1,1,jim,2
    2,1,grace,2
    3,2,tom,2
